摘　　要：非穿透性结构损伤会造成结构承载能力的下降,必须进行及时的修理。采用光固化树脂基复合材料为补片对损伤结构进行粘接修理,研究了基体树脂中环氧有机硅树脂的用量对粘接修理结构承载能力和耐湿热性能的影响。结果表明:环氧有机硅树脂的引入,可以有效地提高复合材料粘接修理的效果,当其用量为15%时,承载能力最佳。随着环氧有机硅树脂用量的增加,粘接修理结果的耐湿热性能逐渐提高。湿热老化后,补片层间剪切强度降低,拉伸破坏时,补片会出现层间破坏。Part-through damage of structure can lead to decrease of the load capacity.It is necessary to repair the damage in time.UV curable composite was patched to the damaged structure.The silicon modified epoxy resin was introduced into the matrix to improve the comprehensive property of composite patch.According to the experimental results,the load capacity of repaired damage structure was increased with the addition of silicon modified epoxy resin.When its content was 15%,the repair effect was the best.The hydrothermal property of repaired structure increased with the increase of epoxy addition.After the hydrothermal treatment,the interlaminar shear strength decreased.As a result,interlaminar failure appeared while the repaired structure failed.
